In reply to AntonY:
I did the K2 BC and Gondogoro La pass trek, over 14 days, with ten of us tourists, a tonne of porters, a bunch of horses, all food, etc, starting from Skardu, for $1,100 each, however that was in 2011. I did a tonne of research, as there’s myriads of companies and found Snowland Treks & Tours to be the best bang for the buck, in terms of not being the cheapest, but fairly cheap, however with excellent service. I’ve just checked and our group photo is still on their homepage and my review! As we were a group of ten, we got a particularly good price. It’s worth sending Kamal Hussain an email and see if he’s got any groups lined up for this summer, as you get massive economies of scale on the price in a larger group. I’d highly recommend them. That price didn’t include kit, as we had our own tents, clothing, etc, nor did it include any flights to/from Skardu, however did include the jeep ride Skardu to Hushe and the return ride back from the other side (I forget the name of). Good luck and enjoy Pakistan! It’s truly stunning!!
